Interesting, earlier today when I was responding to a post regarding the evils that governments are capable of, Nagasaki and Hiroshima came to mind.

I want to believe that they did not know the level of destruction they were unleashing upon all living things in those areas. But when I dare to be honest with myself, I have to think that they may have been hoping for something 100 times worse. As long as it wasn't unleashed on their own lands, and communities. The way they were able to wipe out whole generations of families. Destroying the innocents that had no say, and all things that lived in the area.

Scarier than having to come face to face with Satan himself, is knowing that kind of evil can live in the heart and souls of mankind. That man is willing to destroy every living thing on this planet, just to claim victory. Even if he along with everything else is killed in the process. Makes Satan look like a saint.
